I build focused, privacy-respecting apps and native Mac tools. From podcast queues and movement logs to MP3 tags, Git history, databases, and icon workflows, everything stays local-first, clear, and lightweight.
Podcasts, collections, movement, and media files all stay understandable and under your control — without accounts, ads, or mystery sync layers.
A modern, open-source podcast player that keeps podcasting free, open, and independent.
Catalog your video game collection and carry it across all your Apple devices.
Your day as a clear timeline of places and movement — and none of it ever leaves your phone.
Inspect, fix, and organize MP3 metadata without guesswork.
Clean whole album or podcast drops in one pass.
Jump through timestamps instead of guessing blind.
Automate repeated tagging steps on your own workflow.
Borrow and lend tools with the neighbours around you — instead of everyone buying their own.
Sign up with your name and street — your address is never shared publicly.
Add the tools you're happy to share, or see what your neighbours have posted.
Send a short message, agree a time to collect, and you're done. Neighbourly sorted.
Native macOS utilities for the things I do all day — Git, Swift, REST APIs, databases, app icons, and custom SF Symbols.
Import any SVG and export a custom SF Symbol that drops straight into Xcode.
Your Git history, always one glance away in the menu bar.
Find and remove unused Swift code — without losing control of your source.
A simple, native REST client for testing your APIs.
Newer Mac releases sit alongside the small utilities that quietly keep doing one job well.
Browse and edit SQLite, MySQL, PostgreSQL, and Supabase data with staged SQL review, saved queries, and scheduled monitors. The iPhone version is on the way.
Edit Apple .icon bundles, tune vector layers visually, and export print-ready PDFs or production assets.
Launch apps and scripts automatically on the schedule you choose, so recurring Mac chores happen without babysitting.
A menu-bar network-quality monitor with a traffic-light indicator, manual baselines, and CSV export for later analysis.
A second clock for any time zone in your menu bar, including less usual formats like .beat time, earth time, and UNIX timestamps.
Reusable Swift Package Manager libraries I've pulled out of my apps — free to drop into your own projects. Each app's full source is linked from its own section above.
Check whether your iCloud CoreData/SwiftData store has finished syncing, by comparing live records against a known entry count from key-value storage.
SwiftCustom SF Symbols for game consoles and platforms, with a region-aware platform → symbol lookup. Powers Game Collector.
SwiftDetect the current device style — iPhone notch or Dynamic Island, iPad, Apple Watch, Vision Pro, Mac — and get the matching SF Symbol.
SwiftA simple Ken Burns pan-and-zoom effect for any SwiftUI view.
SwiftA Swift API wrapper for howlongtobeat.com to fetch video-game play times.
SwiftThe barcode database behind Game Collector — it turns a game's UPC/EAN barcode into its title, platform, and release region. There's a free public endpoint to test against, and a full API for serious integrations.
Send the EAN/UPC as the query string. The API replies with JSON — an array of matches, since one barcode can map to more than one release. An empty array [] means no match was found.

]I've been building apps since 2009, with my first App Store release in 2010. By day I'm an aerospace engineer; in my spare time I build small, focused apps for iPhone, iPad, and Mac. I care about software that stays local-first, respects your privacy, and doesn't lock you in — so most of my apps are free, and many are fully open source.
